it may concern;

, means for producing certain given sounds through-ahorn.

The invention is.particularly adapted for i use on automobiles or other vehicles in -tures of the invention.

sounding an alarm.

In the accompanying drawings :Figure 1, is a side View of my improved device illustrated in connection with an automobile horn; Fig. 2', is a lan view; Fig. 3, is a sectional view on the l ine 3-3, Fig. 2; and Fig. 4, is a perspective view of a portion of the device.

The invention can be used in connection with any sound reproducing mechanism, and, in the drawings, I have illustrated a graphophone construction using a cylinder uponwhich are the indentations for produc ing given sounds. This device is preferably placed in close proximity to the seat of the automobile driver so that he can operate the lever-in place of the air bulb, although the device can be placed at any point and the lover actuated throughoperating mechanism without, departing from the essential fea- The horn can be placed atilany convenient point and con nccted with the instrument by any flexible tubing.

A is the base upon which the graphophone is mounted.

. the base plate of the graphophonc and B' -B are the vertical supports for the mochan'isn'i.

C isthe drum on which the tubular record r;- is mounted.

L, D-is the feed screw for traversing the carrier E.

I? is. the main shaft on which is mounted the ratchet wheel f, which is engaged by a pawl f 'on a gear wheel F loosely mounted on the said shaft F. A train of gears transmits the motion from the gear wheel F to a pinion (l on the shaft-D. On one of the intermediate shafts is a belt pulley around which passes a belt for driving the drum C. On the carrier E is mounted the speaker 0 having the needle which contacts witlrthe record.

G and H are two bars whichare parallel with the screw shaft D and are supported at their outer ends, as well as the screw shaft by a bearing B I is the governor for limiting the speed of the mechanism.

All of the above described mechanism forms part of an ordinary graphophone.

In place of using the entire record a given portion of the record may-be used'over and over again as by the mechanism which I will proceed to describe the carrier E is traversed forward by the screw and returned to its original position by a spring. lflfor instance, a section 01' a bugle call is on the record, the speaker can be so set in respect to the record that the bugle call can be repeated over and over again .as the mechanism is operated by the chaufYcur to sound an alarm; taking the place of the usual practice of blowing a horn.

M is the horn which may be of any suitable type connected by a flexible tube m to the end (2' of the carrier which communicates with the speaker so that any sound produced at the speaker will be' passed through the horn.

L is the operating lever pivoted to the shaft F. as clearly illustrated in Fig. 3. This lover is fastened to the shaft and when moved in a forward direction as shown by the arrow. Fig. 1, turns the shaft and through the medium of the ratchet f, the rear F in the direction of the arrow, Fig. 3, thereby driving the record, and at the same time turning the SCI'CW shaft D and feeding the carrier forward so that the speaker will pass at the proper speed over the face of the record thus producing the sound recorded on the record. the lover I! toward its normal position the rafr-hct wheel f moves past the pawlif Without turning the wheel F.

Pin-ted at n to the Frame 13 is a rocker whirl] is actuated by :1 pin 1 on the lever l1 striking one arm of the rocker at n as the lever nears the end of the forward stroke. When the lover is returned it strikes the rocker at n shifting it to the position indicated in Fig. 1. This rocker N is connected by a link N to a lever K pivoted at It to the base of the machine and this On the return movement of.

lever has a projection is which extends through a slot a in thelink N 50' as'to provide a certain amount of lost motion.

one arm of the lever K engages one arm 5 of the lever J pivoted at j to the base of the machine and this lever has a projection j which eei'tends into a slot 7) in a rocking lever P pivoted at p" to the hearing B". This rocking lever has an extension P in 10 which travels one arm of a lever E which is mounted on the h'nlie of the carrier and is arranged to throw the threaded lever B into and out of gear with the screw shaft 1) so that when the qierating lever L is thrown over to its forward position the projection Z on the lever will strike the rocker N and the motion willhe communicated to the .rocking lever I, throwing the threaded leverFEnout ofpaesh with the threads on the screw shal'hdf stopping the forward movement. of the carrier. A spring 9 on the rod G returns the carrier to its original position against a stop g on the rod so that when the carrier is moved forward again the bugle call or other record will be repeated; the spring being compressed on the foe ward movement of the carriage. hen the lever T1 is returned to its normal position shown in Fig. 1, it actuates the rocker N and resets the threaded lever E into engagement with the screw shaft so that on the forward movement of the lever the Speaker will immediately travel over the record; reproducing the sound.

WVhile] have shown my invent ion as adapt ed for use in a grapl'iophone of the type illus trated, it will he understood that the mecha nism for producing sound may he varied without departin; from the essential tea 40 tures of the invention.

While T have illustrated and (ll-4'lllu nl two levers K and J for transmittin; motion from one. end of the machine to the other. it will he understood that in some types of machines the gearing may he changed so that a single lever may be used for actuating the rockin lever P.

Certain of the details of construction may be n'lodified without departing from the essential features f the invention the onstruction will depend materially upon the type of soundproducing in lrun'wnt used.

it witl thus h seen by the ahovr descrihwl invention that any short. record an he re prraluced as a signal warning on an llllltlmobile or other which and that tin record an he repeated as otlen as desired.
